This how you set the equation up.
2x + 6 = 3x + 7
Subtract 6 from both sides.
2x = 3x + 1
Subtract 3x from both sides.
-1x = 1
Divide.
x = -1.
Now solve for y by plugging in the variable.
y = 2(-1) + 6
y = -2 + 6
y = 4
So your solution is (-1,4).
I hope this helps love! :)

Answer and Step-by-step explanation:

Each unit is equal to each other, and we know that both allowances together equates to 72, so if we divide the amount of units that there are, we can determine the amount per month.

There are 8 units in total.

72 divided by 8 = 9

Now, we do 9 times the amount each person has.

You = 5 * 9 = 45

Friend = 3 * 9 = 27

A segment with endpoints A (4, 2) and C (1, 5) is partitioned by a point B such that AB and BC form a 1:3 ratio. Find B.

Furkat [3]

The coordinates of point B that divides the line in the ratio 1:3 is: ( C )(3.25, 2.75)

<h3>What is a line segment?</h3>

A line segment is formed by joining two points by a straight line.

Analysis:

The coordinates of point B(x,y) are gotten by the formula

x = $\frac{px2 + qx1}{p+q}$

y = $\frac{py2 + qy1}{p + q}$

where, x1 and y1 are coordinates of A and x2 and y2 are coordinates of B

are the values of the ratio p:q.

x1 = 4, x2 = 1 y1 = 5, y2 = 2, p = 1, q = 3

x = $\frac{(1 x 1) + (3 x 4)}{1 + 3}$ = 3.25

y = $\frac{(1 x 5) + ( 3 x 2)}{1+3}$ = 2.75

coordinates of B are ( 3.25, 2.75)

In conclusion, the coordinates of point B are (3.25, 2.75)

Sweaters cost $42 each .For every 5 sweaters You buy,You get 1 sweater free.How much will a total of sweaters cost ?

solniwko [45]

Note: I think you may have unintentionally missed to mention the amount of total sweaters for which we have to measure the cost. So, after a little research, I was able to find the complete question. So, I will answer your question based on the following completing question. Anyways, it would clear your concept hopefully.

Here is the complete question:

Sweaters cost $42 each. For every 5 sweaters You buy,You get 1 sweater free. How much will a total of 30 sweaters cost?

Answer:

The cost of 30 sweaters = $1050

Step-by-step explanation:

What to determine?

How much will a total of 30 sweaters cost?

Information Fetching and Solution Steps:

The cost of each sweater = $42

For every 5 sweaters You buy, you get 1 sweater free. It means you will be able to get 6 sweaters for the price of 5

The cost of 6 sweaters ⇒ The cost of 5 sweaters + 1 free = 42×5 = $210

If the cost of 6 sweaters = $210

Then

the cost of 30 sweaters = 210 × 5 = $1050

Therefore, the cost of 30 sweaters = $1050
